' Application filed May 20,

The object of the invention is to produce a simple, compact and effective governor for the purpose above specified, said governor being adapted to be mounted upon and actuated by any rotatingshaft or element of the engine and connected'with the throttle valve for actuating the latter in such manner as to prevent the racing ofthe engine when relieved suddenly from its load, either in whole or in part. 7 V

A further object of the invention is to so construct the governor that it maybe readily applied to engines already in use in any easy and expeditious manner.

With the above and other objects in view, the invention consists in the novel construction, combination and arrangement of parts herein fully described, illustrated and claimed. I,

In the accompanying drawings Figure 1 is an enlarged diametrical sec-' tion through the governor; V

Fig. 2 is a plan view of the rotary engine driven member of the governor.

Fig.3 is a vertical longitudinal section throughthe rotary member, shown in sepa ration from the engine, and illustrating the associated movable centrifugal control members and plunger.

Fig. 4: is a detail view of one of the centrifugally controlled members.

Fig. 5 is a plan view of the same.

Fig. 6 is a detail view of the plunger. guide.

Fig. 7 is an end view of the same.

Fig. 8 is an inner end view of the plunger.

The governor which is particularly designed for use upon internal combustion engines, gas engines and the like, comprises in the preferred embod'nnent thereof an en gine driven rotary member 1 which is preferably of disk shaped formation as illustrated in Figs. 2 and 3. The member 1V is preferably mounted upon arotary shaft 2 of the engine as shown in Fig; 1 and em- Speeification of Letters Patent. Patented A11 31, 1920,

bodies a plunger 3 the motion of-which is impartedto a throttle valve operating rod 1 by means, for example, of a lever 5 fulcrumed at 6 on an arm or bracket 7 proectmg Irom the engine frame as shown in Fig. 1; the said rod l being designed to be connected with the operating arm of a throttle valve (not shown); The plunger. '3 is mounted for endwis'e movement in a guide 12 which is shown in the form of a tubular post secured at one end by means of fasteners 13 such as screws to the member 1. The guide 12- therefore has a fixed relation to the center of the rotary member 1. The lower arm of the lever 5 is opposed to the plunger 3, and saidfplunger ii is yieldingly pressed in an inward direction or toward the mem- 15 threaded in a housing 16 inclosing the governor mechanlsm all'as shown in Fig. 1. The spring 1% 1s 7 socketed in and held against lateral deflection by the lever 5 and screw 15. Theplunger is provided at its inner end with inclined cam faces 17 as-best I shown in Fig. 8. The cam faces 17 cooperate'with' cam portions 18 on opposite said members 19, their cam portions operate to move the plunger 3 endwise toward the.

right in Figs'l and against the action of the spr ng 1%. Incidental to the outward movement of the members 19, the spring 14 serves through the lever 5 to press the plunger 3 'endwise'toward 'the'leftin Figs. 1 and Each of the members 19 is guided in its back and forth movement by a plurality of anti-friction rollers 20 through which are inserted headed and shouldered screws 21 threaded in the inner side of the respective member 19 as shown in Fig. 3. The rotary member 1 is provided with radially elongated slots or guideways 22in which the rollers 20 operate." In this way the centrifugally controlled members 19 are held in a certain relation to the rotary member 1.

Each member 19 is provided with a plu- 'rality of raised surfaces or projections 23 on tongues 24 which are slidable through an 7 opening in the guide 12, such opening, indi- 7 speotive members 19/ The springs 26 yield under centrifugal action to permit the members 19 to move outward in a radial path.

In view of the foregoing description taken in connection withthe accompanying drawings, it will now be seen that as the speed of rotation of the engine shaft increases the speed of the member 1 also increases and the centrifugally controlled members 19 start to move outwardly toward the periphery of the member 1. As members 19 move out the 7 spring 14 moves the plunger 3 inwardly,and

' incident thereto the speed of the engine is automatically prevented from racing. As

7 the speed reduces, the reverse operation takes effect and the members 19 permit the.

plunger 3 to move in the opposite direction 7 ithereby movingithe throttle valve 9 again toward an open position. 7 V

The speed regulating screw 15 isthreaded through an opening in the housing 16 as shown inFig, 1." The-inner end of the screw 7 15 is formed with a'recess 30 to receive one end of a spring 1% while the opposite eX- tremity of said spring is received ina recess 31 in the adjacent end of the lever 5. Therefore'by adjusting thefscrewfl5, the

r 7 spring 14 may be placed under greateror snugly against the 'lunger 3, causing said lever to swing easi y upon the inward or, return movement of the plunger 3, the lever less tension for regulatingthe resistance to the movement of the plunger 3.. The spring 14 serves tokeep the end of the lever .5

5 thereby immediately controlling the connection 4 which controls the'throttle valve of the carbureter in the manner illustrated in the drawings. The housing 16 incloses the governor mechanism and protects the same against dirt, dust and other foreign matter. The speed screw provides for a wide variation in the speed of, the engine and enables the speed of the engine to be regulated at the will of the operator without requiring the engineto stop for that purpose. 7 a

The governor hereinabove described is simple in construction, reliable in operation and exceedingly compact and will be found a valuable adjunct to a motor vehicle, as it prevents racing of the engine and the injuryincident thereto while at the same time saving materially 1n the amount of gasolene or other fluid fuelnsed in the operation of the engine. This is particularly true in the case of lnexperienced operators of motor vehicles who by improper throttling 'ofthe engine.

waste considerable gasolene,'cause the 'engine to overheat and also cause a rapid'accumulation of carbon'in thecombustion cham-.

ber and valve chambers of the engine.

I claim:-' The combination in a governor, of a radially-slotted disk-like motor-driven rotary member, a housing in which said 'mem-- ber iis disposed, centrifugal members held to the face of the rotaryv member by means movable in the slots of the latter and yield- .ingly held against outward movement, said centrifugal members having inner lapped cam portions, a tubular guide carried by V cam portions are movable, a central endwise movableplu'nger in "said guide and having a cam portion opposed to the cam-portions of the centrifugal members, a lever mounted in the housing and movable by said plunger,
